2 / 20 page 2002 Mar 11 2 Philips Semiconductors Product specification Multiple voltage regulator with power switches TDA3682 FEATURES General • Good stability for any regulator with almost any output capacitor • Five voltage regulators (BU5V, illumination, AM, FM and audio) • Mode selection by three enable control pins • Low dropout voltage output stages (PNP output stage) • High ripple rejection • Low noise for all regulators • Two power switches (power antenna and power control function). Protections • Reverse polarity safe (down to −18 V without high reverse current) • Able to withstand voltages up to 18 V at the output (supply line may be short-circuited) • ESD protection of all pins • Thermal protection to avoid thermal break down • Load dump protection • Regulator outputs are DC short-circuited safe to ground and supply voltage • Foldback current limit protection for all regulators • Loss of ground protection for power switches. GENERAL DESCRIPTION The TDA3682 is a multiple output voltage regulator with power switches, intended for use in car radios with or without a microprocessor. The TDA3682 contains the following: • Four switchable regulators and one permanent active regulator (BU5V) • Two power switches with loss of ground protection • Three enable control inputs for selecting the regulators (illumination, audio, AM or FM) and the power switches (PANT and PCON); the standby mode is selected with all enable control inputs at LOW level. The quiescent current has a very low level of 120 µA (typical value) with the regulator 2 (BU5V) active.
